What are the odds of a cocked and unlocked 1911 firing when dropped?

[PROCON]

I’m not a 1911 guy, I like Glocks.

Zero if it has an 80 series firing system.

And it is not a 1911, it is one of the smaller lookalikes in 380.

Colt Mustang .380. It’s 1911 downsized. With the safety on it would be safe.

That's a Colt Mustang .380... Almost no chance of it going off when dropped as photographed. Mash the trigger and that's a different story.

[Durus]

Near zero. Plus that is a colt mustang not a 1911.

The older 1911 series had an inertia firing pin that is retracted after firing by a spring that surrounds most of the firing pin body. If the pistol is dropped muzzle down from a sufficient height on a solid surface, then the force of the impact might be sufficient to overcome the inertia of the firing pin at rest within the slide (especially a weak and worn one), causing it to go forward with enough force to detonate a cartridge primer, especially a sensitive one. Such an occurrence is quite uncommon though.

Later model non GI 1911’s utilize a firing pin safety that automatically releases the firing pin when the trigger is pulled just before the hammer strikes the firing pin, and serves to prevent such accidental discharges.

Oops! Misread your question. I thought the safety was engaged which it's not.

I retract my answer.

New answer: I don't know.
